Abstract
Assessing the quality of businesses and improving them accordingly is critical for sustainable competitive advantage. This study focuses on evaluating the dimensions affecting the service quality of sea ports, which contribute significantly to the development of global trade. Therefore, this paper aims to determine the importance weights of the dimensions of the ROPMIS model presented by Thai (2008). In today's world, Fermatean fuzzy sets (FFSs) are a useful tool in many decision-making problems due to the possibility of better capturing human uncertainty and subjectivity. The weights of dimensions of the ROPMIS model are determined with AHP method under the Fermatean fuzzy environment. The suggested approach is an effective means of managing the ambiguities and errors in the data pertaining to the dimensions' weights. In order to provide a tool for assessing and ranking port global quality dimensions that may have an impact on sustainable port service quality, this study serves as a benchmark for subsequent research.
